Building Background Location: 1800 Johnson St. Baltimore, MD. Architecture (Design and Functional Components):

Five story, 170,000 square foot facility

Fourth: Multi-purpose center, computer classroom, office space, auditorium, and three formal lobbies

Third: Tenbroek Library and Research Center and classrooms

Second: 36 classrooms, office space, and archive storage

First: Parking garage with main lobby and foyer (Southern portion at street level with the northern portion below grade)

Lower level: Parking garage (below grade) with storage space

Building’s Function Enable the disseminate the

latest teaching techniques to teachers of the blind.

Educate parents of blind children of the cutting edge technology upon which their children’s success hinges.

Inform adults and older people losing vision the ease of learning Braille.

Foster the direction and growth of adaptive technologies through a dedicated incubator center, to develop new ways to utilize computer systems with speech and Braille.

Area of Study*

Topics of Discussion Lighting Computer Classroom (2 options and

cost comparison) Emergency Power Redesign (electrical

breadth) Lighting Multi-purpose room Acoustical study Daylighting Study in Lobby and Atrium Lighting Lobby and animation

Lighting Design Criteria for the Partially Sighted Safety issues: Clearly define

circulation and emergency egress patterns without using distracting patterns.

Eliminate Glare: Keep bright luminaires out of occupant’s field of view (direct and reflected)

Increased Illuminance: For certain disabilities, 2 to 3 times the recommended ambient level will be required for visual tasks.

Adaptation Sensitivity: Introduce changes in illuminance level in a slow, comfortable fashion.

Contrasts: Increase luminance ratios of near to far field objects without creating glare.
